QuickTime Player on Yosemite will not capture HTTP live broadcasts with encrypted media during screen recording. In the recording, these will be blacked out. Live HTTP Streaming: It uses Apple’s HTTP live streaming (HLS) technology to transmit live and on-demand music and video to iPhone, iPad, Mac, Apple TV, and PC. HLS, which uses the same protocol as the web, allows us to publish content using standard web servers and content delivery networks. HLS is built for scalability and constantly adjusts to network conditions by optimizing playback for wired and wireless connection speeds.
